google/eve: Set touchscreen I2C bus speed to 1MHz
Enable Fast-Plus speed for the touchscreen device so it can be used at 1MHz instead of 400KHz. BUG=chrome-os-partner:61277 TEST=manual testing on Eve P1, needs backported kernel patches to actually make use of any I2C speed other than 400KHz Change-Id: I3f44ff4a02a02a7b05e69ad54d4c6d60e5878393 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/18397 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
